Analysis of 90 Cases of Antithyroid Drug-Induced Severe Hepatotoxicity Over 13 Years in China
Abstract
BACKGROUND: Antithyroid drug (ATD)-induced severe hepatotoxicity is a rare but serious complication of ATD therapy. The characteristics of severe hepatotoxicity have been reported in only a small number of patients. METHOD: Ninety patients with ATD-induced severe hepatotoxicity presenting during a 13 year period (2000-2013) who were about to undergo nuclear medicine therapy with (131)I from a sample of 8864 patients with hyperthyroidism were studied, and the outcomes were evaluated. RESULTS: The mean age of the patients with ATD-induced severe hepatotoxicity was 41.6±12.5 years (mean±standard deviation), and the female to male ratio was 2.2:1. The methimazole (MMI) dose given at the onset was 19.1±7.4 mg/day. The propylthiouracil (PTU) dose given at the onset was 212.8±105.0 mg/day. ATD-induced severe hepatotoxicity occurred in 63.3%, 75.6%, and 81.1% of patients within 4, 8, and 12 weeks of the onset of ATD therapy, respectively. The types of severe hepatotoxicity did not differ significantly between the MMI and PTU groups (p=0.188). The frequency of the cholestatic type in the MMI group (35.3%, 18/51) was higher than that in the PTU group (17.9%, 7/39), but these frequencies were not significantly different (p=0.069). The patients who were treated with (131)I received an average dose of 279.1±86.1 MBq (n=84). Therapy was successful in 60 of the 67 patients (89.6%). The success rate was equivalent (p=0.696) between the groups receiving MMI (91.7%, 33/36) and PTU (87.1%, 27/31). CONCLUSIONS: Severe hepatotoxicity tends to occur within the first three months after the onset of ATD therapy. The type of ATD-induced severe hepatotoxicity did not differ between the MMI and PTU groups. (131)I therapy is an effective treatment approach for patients with ATD-induced severe hepatotoxicity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
